Key State Department official resigns in wake of Benghazi report

The assistant secretary of state for the Bureau of Diplomatic Security has resigned and three other officials have been relieved of duty after a report criticized the State Department over the attacks on U.S. diplomats in Benghazi, Libya, the department said late Wednesday.

State Department spokesperson Victoria J. Nuland confirmed that Eric Boswell had resigned and said three other officials had been relieved of duties pending . Two of the others worked in the Bureau of Diplomatic Security and one in the Bureau of Near East Affairs.

Nuland did not name the other three, but a U.S. official told NBC News that one was Charlene Lamb, Boswell’s deputy assistant secretary of state for international programs. Earlier reports had said that Boswell, Lamb and another unidentified official had resigned.

The resignations come after the release of the Accountability Review Board Report on the attacks on the U.S. Mission in Benghazi, Libya, which faulted the State Department and specifically the Bureau of Diplomatic Security for "grossly inadequate" security.

Here’s Nuland’s full statement:

"The ARB identified the performance of four officials, three in the Bureau of the Diplomatic Security and one in the Bureau of Near East Asia Affairs. The Secretary has accepted Eric Boswell's decision to resign as Assistant Secretary for Diplomatic Security, effective immediately. The other three individuals have been relieved of their current duties. All four individuals have been placed on administrative leave pending further action."
